What is the difference between Line of Sight, Near Line of Sight and NON Line of sight?
LOS: So in order to have clear line of sight (LOS) you not only need to be able to see the other side but the Fresnel zone needs to be clear of any obstructions. nLOS: If there are some minor obstructions penetrating the Fresnel zone this would be considered as a near line of sight (nLOS) application. Most bridges these days will perform rather well in nLOS scenarios but you will see some performance degradation depending on the number of obstacles and how deep they penetrate the Fresnel zone. NLOS: If you can not see the other side then this is considered non line of sight (NLOS). Putting all the marketing aside it is practically impossible to achieve a solid wireless link under these conditions with regular WIFI bridges. The only bridge that has been proven under these conditions is the Motorola PTP 400 and PTP 600 series bridges.
